Abstract

The invention provides a juvenile coilia ectenes feed additive and a preparation method. The additive is prepared from the following raw materials: chitosan, digestive enzyme, carriers, lysine, glycine, glycine betaine, tea polyphenol, organic selenium, vitamin C, fish oil, emulsifying agent, sodium alginate, gelatin and citric acid. The preparation method comprises the following steps: preparing the digestive enzyme into a digestive enzyme solution, adsorbing with the carriers, then adding the sodium alginate, the gelatin and the citric acid into water, heating, preserving the heat, adding the emulsifying agent while stirring to obtain a mixed solution, adding the digestive enzyme carrier solution, the chitosan, the lysine, the glycine, the glycine betaine, the tea polyphenol, the organic selenium, the vitamin C and the fish oil into the mixed solution, homogenizing at the high pressure, spray drying, and preparing the feed additive. The additive provided by the invention provides sufficient nutrition to the juvenile coilia ectenes, can increase the survival rate of the raised juvenile coilia ectenes, capable of enabling the juvenile coilia ectenes to have the raising value, capable of improving the fertilizer efficiency and capable of decreasing the feed coefficient.

Description

technical field [0001] The invention belongs to the technical field of aquatic fish feed, and in particular relates to a feed additive for young swordfish and a preparation method thereof. Background technique [0002] Yangtze anchovy (Coilia ectenes Jordan et Seale), commonly known as saury, mackerel, wild hairy fish, plum anchovy, etc., together with Changjiang shad (Tenualosa reevesii) and puffer fish (Takifugu), are also called "three delicacies of the Yangtze River". Sword anchovy is a migratory fish that usually lives in the sea. It enters the river from the sea from February to April every year, and goes up the river for reproductive migration. Spawning populations enter lakes and tributaries along the Yangtze River or carry out spawning activities in the main stream of the Yangtze River. Due to increased pollution in the Yangtze River and overfishing, the output of Yangtze saury has been declining year by year. Moreover, the population and individual miniaturizat...
